IMPROVEMENT IN SHUTTER-FASTENINGS.

Specification forming part of Letters Patent No. 152,696, dated June 30,1874; application filed June 9, 1874.

To all whom it may concern:

Be itknown that I, WILLIAM E. SELLEcK, of St. Louis, in the county ofSt. Louis and State of Missouri, have invented certain new and usefulImprovements in Fastening for Iron Shutters, of which the following is aspecification f This invention relates to an improved arrangement,whereby the ordinary iron shutters used on buildings as a protectionagainst Iire, can be opened readily from the outside of the building,thus enabling firemen to have access to the re in the building in caseof a conliagration. It consists in pivoting one end of a bar to one ofthe shutters, the other end of the bar engaging under a catch on theother shutter to lock the shutters when closed. Said bar is supported ona pivoted trip-lever, having a down-turned wing upon the outside of the`shutter andprojecting outwardly, and which, when pushed aside (by astream of water from j a lire-engine) will trip the bar so as to let itfall, and disengage it from its catch; the shutters may then be openedby directing a stream of water under the edge of the shutters 5 or aninclined projection may be arranged on one of the shutters, as shown,which the bar strikes in its descent, and partially forces said shutteropen; or a spring may be arranged between the subsill and one or both ofthe shutters, so as to force one or both of the shutters open; or thebearings of the hinges may be inclined so as to cause the shutters toopen by gravity when unlocked.

I Figure l is a perspective view of the inside of the shutters. Fig. 2is a detail section.

A B are the shutters formed of sheetiron plates riveted to rectangularframes a. b. C is a bar hingedat c to the shutter B, and engaging undercatches D secured to the shutter A. Said bar is guided by a guide strapor staple E secured to the shutter B. The bar C is held or supported inengagement with the catches D by'a trip-hook, F, engaging a hooked lug,G, on the said bar; the shaft of the hook F passes out through theshutter, and is provided with a downwardly projecting plate or wing, H,which, when oscillated or moved to one side, disengages the trip-hook Ffrom the lug G, and allows the bar C to descend out of engagement withthe catches D so as to unlock the shutters. By this arrangement theshutters is unlocked, and may be opened by directing the stream of waterfrom the re-engine under the-edges ofthe shutter 5 but I prefer to usesome positive arrangement for opening (partially) the shutters, such asis shown in the drawings, in which I is an inclined projecting angle-barsecured to the shutter A, which causes said shutter to open when the barC descends and strikes against it. Instead of the inclined bar I beingused, a spring may be substituted to force the shutter partially open,when the bar O is disengaged from its catches D 5 or the bearings'of thehinges may be inclined so as to open the shutter by gravity when the barO is disengaged from its catches, D.

The operation of my improved device is as follows, (the drawingrepresenting the shutter closed and lockedz) If required to open theshutter a stream of water from the reen gine is directed against thependent wing II, which is forced aside, disengaging the trip-hook F fromthe bar O, which latter descends, striking' p against the inclinedprojection I, forcing the shutter A partially open. The further open ingof both shutters is accomplished by a stream of water from the enginebeing thrown behind them.

I claim asm y invention-- l. The bar O in combination with a pivotedtrip, having a down-turned wing on the outside of the shutter,substantially as and for the purpose set forth.,

2. The pivoted bar C and catch D in combination with any suitabletripping device, and inclined projection I, substantially as set forth.v 3. The combination and arrangement of the bar O, catch D, guide-strapE, pivoted trip F,- G, H, and inclined projection I, as and for thepurpose set forth. l
